What causes AC compressor to explode?

The most likely cause of these explosions is the ingress of air into the refrigerating system and high operating pressures, if the air conditioner is leaking on the suction service valve it could potentially turn into a bomb! The increased pressure and temperature can cause the compressor to overheat and fail.

What can damage an AC compressor?

These are the common issues that cause AC compressor failure:

Dirty coils.
Blocked suction lines.
Low refrigerant charge.
Incorrect suction line size.
Too much refrigerant.
Electrical problems.
Contaminants in the system.
Inadequate oil lubricant.

What are the symptoms of a bad AC compressor?

One of the first signs which is really to recognize symptoms of bad AC compressor is the AC no longer blowing as cold as it did. A damaged or failing compressor will not be able to properly regulate the refrigerant flow in the AC system, and as a result, the AC will not function properly.

Why does the air conditioner keep blowing the high pressure hose?

Once the RPMs are elevated that high side pressure will drop even more; sans a restriction in the lines or condenser. The only reason I can think of for a hose to repeatedly be blown off would be if the threads in the affected area are stripped to some degree.

What happens when your a / C compressor is over charged?

It seems very simple though. If your a/c system is over charged and is creating too much pressure, your compressor will turn (cycle) off, and when that happens you’d probably notice a slight change in temp as long as you have your a/c crankin. As soon as the pressures fall and return to a safe range, the compressor cycles back on.

Why did my air conditioner compressor blow the second time?

Just went out to check a few things and even with the a/c off the compressor was running (explains why it blew the second time), I pulled the 267 relay which I’m sure is the a/c relay and it still was running, didn’t want it to blow again so I just unplugged the compressors green connector by the PS res. which did shut it off thankfully.

What does it mean when air conditioner compressor is full blast?

An air conditioner or heat pump compressor pulls a high amp draw on startup, which is technically called locked rotor amps. The compressor has to start from a full stop to full blast in less than a second.

What should I do if my air conditioner blew a fuse?

The compressor should blow the fuse or trip the circuit breaker when power is turned back on. But watch out: we get field reports of equipment burn ups and even fires when the air conditioning circuit breaker for the compressor happens to be an old FPE Stab-Lok or Zinsco unit.
